Equivariant commutative stringy cohomology rings on almost complex manifolds

Bohui Chen, Cheng-Yong Du, Tiyao Li

In this paper, motivated by Chen--Ruan's stringy orbifold theory on almost complex orbifolds, we construct a new cohomology ring ${\mathcal{H}}_{G,cs}^{\ast }(X)$ for an equivariant almo…
